Great pistol, I've sold lots of them.
The trigger pull is a crap shoot, some are decent out of the box some are horrendous. Changing the main spring makes things a lot better and some dry firing smooths things up considerably. I use Wolff springs and have been very happy with them.
If you have small hands I recommend getting the E2 kit (though you need the plastic base and new style trigger bar spring) Its well worth it for those who have short thumbs on the mag change.
